A method of depositing a thin film on a surface by evaporation within a vacuum chamber which includes a discharge source of electromagnetic energy for effecting cleaning of a said surface includes the steps of reducing the pressure within the chamber to approximately 10<SP>-5</SP> Torr, energizing said energy source, leaking gas into the chamber to raise the pressure therein to approximately 5 x 10<SP>-5</SP> Torr to enable a discharge from said source to be sustained; during said discharge heating the evaporant and confining heated evaporant in an enclosure, and releasing said heated evaporant after a predetermined time whereby the evaporant is deposited in thin film form on the surface. One or more layers may be deposited; substrates mentioned are glass, Si, Ge, arsenic triselenide and arsenic trisulphide; the coating may be MgF 2  or Al and the atmosphere air.

Abstract: 1516417 Camera shutters SEIKO KOKI KK 2 Dec 1975 [3 Dec 1974] 49430/75 Heading G2A A camera shutter has a resilient device 9 for engaging a leading portion of a blade 5a to brake it and prevent recoil, and an abutment 2c engageable with a trailing portion of the blade to damp vibration of the blade perpendicular to its plane. As shown the shutter comprises an opening blade system 5 and a closing blade system (8) Fig. 1 (not shown). The opening blade system 5 comprises a slit forming blade 5a pivoted by pins 4b, 3b to a parallel linkage 3, 4 which moves blade 5a rectilinearly. A pin (3c) on the linkage 3, 4 pivots blades 5b-f to follow the slit forming blade 5a. The closing blade system is similarly constructed. When the blades 5 move to open the exposure aperture 2a the pin 4b on the slit forming blade 5a engages a bent portion 9a of a spring plate 9 to brake the blades 5 and prevent recoil. Any vibration of the blades 5 is damped by an abutment 2c located over the pin 3b.
